I have seen some pics on here and on the net of big barbeque grills/pits made from LP tanks (the big ones that are like 30"+ in diameter and about 5 feet long). I have found a tank on our farm that isn't being used for anything and am thinking about making a bbq grill. What do I need to consider before starting in? I know you really need to purge the tank before cutting (from what I can tell, water is the best for this).
Here are my big questions right now:
What is the best way to cut the openings for the doors, pipes, vents, etc? Will a cutting torch cut through the steel wall of the tank while the tank is full of water?
Which is better, one door or two? This tank is at least 5 feet long, maybe more. I'm guessing one door would be at least 4 feet long. I don't know how thick the metal is, but I'm guessing that a door that big would be pretty heavy.
Direct heat or indirect heat? I know quite a bit about BBQ, and I can see the merits of both types of cooking. Is it possible, or even reasonable to try to design and build a cooker for both types of cooking?
Any other thoughts or experiences you fellas can relay to me on this subject would be greatly appreciated.
